Garmin ended factory support for the 28 volt-only GNS-430 on September 30, 2010. As a result, we do not expect to have any 28 V-only GNS-430s in the future, and this product should be considered discontinued from our inventory. (We will leave this web page online to provide information for the General Aviation community.)

The 14/28 volt version of the GNS-430 remains fully supported.

It's not a stretch to say that Garmin's GNS-430 has revolutionized general aviation avionics. It combines a variety of avionics capabilities with the power of modern computers, to provide both sophistication and ease of use.

The GNS-430 contains and integrates the following functions:

IFR GPS

Jeppesen database

COMM

VOR/LOC

Glideslope

Moving Map / MFD

In addition to the color map, the GNS-430 can also display lightning data from a remote WX-500 Stormscope, weather data received via satellite, and traffic from a GTX-330 Mode S transponder.

Garmin also protects the GNS-430 from future obsolescence, with an available WAAS upgrade.
